f33330c0ff arm: factor all exception handlers out of the crt0.S files 
Remove the implementations of all exceptions handlers from the
various crt0.S files and have a single implementation in system-arm.h
The new implementation is weak so that it can be overwritten by some
specific code (like the unwinder)

b4eab59951 Arm stack unwinder 
Simplified stack unwinder for ARM. This is port of
http://www.mcternan.me.uk/ArmStackUnwinding/
backtrace() is called from UIE() on native targets
and from panicf() on both native and ARM RaaA.

f34a841b0c Revise r23225 a bit, removing the debug_printf function and implementing more generic lcd_(remote)_putsf function(s) instead and use those in more places

ccb52bd72c Make the panic and UIE handlers turn on the backlight (needed for various colour LCDs that are unreadable without it). UIE is only changed on ARM for now.

4ed78f5c72 Clean up panicf and introduce system_exception_wait to do further target tasks and wait for a button when an unrecoverable error has occurred (panic, UIE, etc.). Returning from that function should reboot or don't return from it. Move UIE and __div0 for ARM to its own file.
